TSA’s routine screening of checked baggage immediately flagged the suitcase. After inspecting the contents, officials unzipped the bag’s lining to find the gun strapped to the frame.

Port Authority Police immediately confiscated the weapon. Police arrested the man on weapons charges at the airport terminal before he boarded his flight.

TSA regulations allow travelers to travel with firearms in checked baggage as long as they are unloaded and properly packed in a locked, hard-sided case. All weapons must also be declared with paperwork.

It wasn’t immediately known why the man didn’t declare the weapon beforehand.
